Abstract

Cellular light weight concrete (CLC) masonry has gained tremendous popularity in recent decades owing to its sustainability, density, low thermal conductivity and use of less mortar joints. The objective of this study is to develop a high performance fiber reinforced cellular
concrete to provide a better alternative than aerated autoclaved concrete blocks for structural applications of masonry. Use of micro-fibers (Fibrillated) enhances pre-
cracking behavior of masonry by arresting cracks at micro
-scale, while Macro (structural) fibers induce ductile
behavior in post-peak region by arresting the crack propagation soon after the crack initiation. In particular, the mechanical behavior of CLC cylinders under pure compression, CLC blocks under flexure and CLC masonry prisms under compression with and without polyolefin
structural fiber reinforcement as well as hybrid fiber reinforcement is investigated.
